IMPROVEMENT I N MACHINES FOR FORMING LININGS FOR AXLE-BOXES.

Specification forming part of Letters Patent No. 133,450, dated November26, 1872.

To all whom it may concern:

Beit known that I, HENRY KELLOGG, of Milford, in the county of New Havenand State of Connecticut, have invented a new yImprovement in Apparatusfor Formingthe Lining for Axle-Boxes 5 and I do hereby declare thefollowing, when taken in connection with the accompanying drawing andthe letters of reference marked thereon, to beafull, clear, and exactdescription of the same, and which said drawing constitutes part ofthisspecification, and represents, in-

Figure 1, a front view; Fig. 2, an end view; Fig. 3, a centraltransverse section 3 and in Fig. 4, a detached view.

This invention relates to a device for forming a sheet-metal liningi'orcarriageaxle boxes, especially designed as an auxiliary device for themachine for lining axle-boxes for which I have led an application forpatent in even date herewith; and it consists in the combination ofrolls with a former and a mechanism for presenting the plate, wherebythe plate, when properly presented, is rolled into a cylindrical form incondition to be inserted into the axle-box.

A are three cylindrical rolls of conical formthat is, corresponding tothe form ofthe boxwhich is usually tapering. These rolls are arranged insuitable bearings B, and geared together, as denoted in Fig. 2. In orderto open the rolls the upper roll A is arranged in a bearing, C, hinged,as at a, so as to be raised from the other rolls, as denoted in brokenlines, Fig. 3, but when in place is locked in position by a hook, D, orother suitable device. The

I rolls are adjusted relatively to each other by set-screws d. Centrallybetween these vrolls and axially therewith a former, F, is inserted, itsouter surface being of the shape and size required for the interior ofthe lining, and is put into gear with' the rolls by a pinion, E, orotherwise, so as to be forced to revolve with the said rolls. H is acarriage arranged upon suitable guides L, upon which the plate to berolled is placed, and thereby properly presented to the rolls, asdenoted in Fig. 3, the plate being shown on the carriage, as in Fig. 4.In the rear of the former a guide, N, is arranged having a concavesurface corresponding to the former to guide. the plate as itis drawnin. The plate is cut to the form required from suitable sheet metal andlaid upon the carriage, as seen in Fig. 4; then, the rolls revolvin g,the carriage is forced forward to present the plate between one of therolls and the former", here represented as the upper roll. The plate istaken by the revolving roll and former and drawn from the carriage; itsedge, striking a guide, N, is bent down around the former, and, passingbetween the successive r 11s and former is wrought into the shapedefined by the former 5 then the rolls are opened, the former with thetube thereon is taken out., the tube removed ready for use, and theformer replaced to produce a second tube by the operation beforedescribed.

While deining this invention as for the lining of axle-boxes-the purposefor which it is especially designed-I do not Wish tobe understood aslimiting this invention to that purpose, as it will be evident Itovpersons skilled in the use of similar machinery that this may beemployed for many purposes.

' I claim as my invention` 1. The revolving rollsAand the correspondingrevolving former F combined with the guide N, substantiallyas'described.

2. In combination with the above, the carriage H for presenting theblank plate to the rolls, substantially as set forth.

HENRY KELLOGG.
